Masquerade is an independent territory outside the jurisdiction of any state. There is no ability to contact the outside world, and tourism and visitation is strictly forbidden. In Masquerade, one’s personal characteristics, including looks, personality, ethnicity, gender identity, and talents, change every day upon waking up, involuntarily and at random (memories are retained as normal). Joining Masquerade through legal immigration is possible, however, once one immigrates, it is impossible to leave.
